What is AWS? 

Amazon Web Services (AWS) is a Cloud Computing platform provided by Amazon. It has become a major part of Amazon's business and is one of the most successful cloud services in the world.

AWS offers a broad range of cloud services, including servers, storage, networking, email, mobile development, and security. Some of its key products include:

a) EC2: A service that provides virtual machines.

b) Glacier: A low-cost cloud storage service.

c) S3: Amazon's storage system.

In the first quarter of 2024, AWS generated £20.25 billion in sales, showing its steady growth. It is now one of the leading cloud platforms, ahead of competitors like Microsoft Azure. AWS is so dominant in the cloud industry that it holds more than a third of the market share, with 31% of the market. Its closest competitors, Microsoft Azure and Google Cloud, have 25% and 11% of the market, respectively.

AWS operates from 105 availability zones, spread across different regions. This helps ensure that services are reliable and secure, with data stored in various locations for safety.
 

 

History of AWS 

AWS was launched in 2002 with a few basic services, and it has evolved rapidly over the years. In 2003, Amazon transformed the platform to standardise and automate its computing infrastructure, focusing on web services and offering virtual servers as a service. By 2004, AWS debuted its first service, Amazon SQS, marking the start of its cloud journey.

In 2006, AWS relaunched with Amazon S3, SQS, and EC2, solidifying its position as a comprehensive suite of core online services. As AWS grew, it expanded S3 and EC2 into Europe in 2009 and introduced Elastic Block Store and Amazon CloudFront. The platform added certifications in 2013 and launched autoscaling in 2018 to enhance resource management.

In 2022, AWS introduced over 110 new features, including AWS CodeCatalyst for app development and AWS Application Composer, a low-code tool for serverless apps. Other highlights included AWS Security Lake, AWS VPC Lattice for enhanced network management, and AWS Supply Chain for streamlined planning.

Today, AWS offers over 200 services, supported by a global network of data centres. With its continuous expansion and commitment to innovation, AWS remains a leading choice for businesses embracing the cloud.

Why is AWS Important?

AWS is important because it allows businesses to use powerful computing resources without having to own or manage expensive hardware. This helps companies save money, as they only pay for what they use instead of buying servers and equipment. AWS provides flexible services like storage, computing power, and networking, which makes it easier for companies to grow and manage their operations efficiently.

AWS offers a reliable and secure platform for businesses to store and manage their data. With many data centres around the world, AWS ensures that services run smoothly and that data is safe. It also helps businesses quickly scale up or down depending on their needs. This makes it a key tool for companies of all sizes.

How Does AWS Work?
